Application Bled January 4, 1919. Serial No. 269,588.

To all whom it may concern:

Be it known that I, VINcE'NT WALSH, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a certain new and useful Improvement in Light Distributers, of'which the following is a specification, reference bein had to the accompanying drawings, which form a part of the same.

The object of my invention is to provide a device for modifying a light and to break up the rays thereof and in connection with the embodiment of my device, I have shown a certain arrangement of reflectors which are calculated to convert as much of the direct light as possible into the modified light.

Referring to the drawings:

Figure 1 is a sectional view of my device taken along the line 11 of Fig. 2; and

lgig. 2 is a plan view of the plate 1 shown In he illustrated embodiment of my invention, I have 'rovided a'transparent plate 1, preferably of glass, which I'hav'e shown sand-blasted at 2. This plate is provided with an aperture or opening 3 therethrough, bordered by the inner edge 4 thereof.

The plate 1 is supported by a suitable frame, that illustrated being constituted of an annular angular ring 5, which is secured to the bracket 6 supported b the metal plate 7 and transparentplate 8. onnected to and depending from the metal plate 7 are housing sections 9, 9 of annular shape which contain an air chamber 10 therebetween, suitable vents 11 being-provided in said housing sections. The housing section 9 is provided with a flange 12 adapted to form a bearin surface for the plate 1 when in position. lower housing section 9 is provided, having a flange 13 adapted to form a bearing surface for the plate 1 0p 0- site to the bearing surface 12. Suite le bolts 14 are adapted to pass through the flanges 13 and '12 and also through the re-. cesses 3 of the plate 1 and thus hold the said housing, plate .1, and. metal plate 7 in a-unitary structure. ally fitted over the lower housing section 9 in such manner as to provide an air the said housin and said cap, suitable vents 17 being provi ed to allow the escape of heat from the structure.

The inside of the housing frame of secsion. The light protrudin A cap 15 is friction-.

tions 9} and 9 is preferably provided with areflecting surface, as are also both sides of the metal plate 7. I have also provided an annular reflector 18 in line with the apertures 19 of the plate 7. 21 is a bracket secured to my device and adapted in any suitable manner to be connected to a ceiling or wall li hting outlet. In the chamber formed lamp 22 is suspended having suitable current conduits 23 leading thereto.

It will, be seen that upon the lamp 22 being lighted, rays therefrom will pass through the edges of the plate 1 and the lower reflecting surface of the plate 7 will increase the light so projected into said plate which is shed therefrom. Light from the lamp will also pass through the apertures 19 onto the reflector 18 and from said reflector to the upper reflecting surface of the plate 7 and from thence through the transparent plate 8, in this way lighting up the upper part of the room where the device is connected to a ceiling fixture and making possible different color schemes according to the color of the transparent plate used. Instead of a plate being used at 8, it is obvious of course, that other trans arent material such as silk may be used. he housing sections 9, 9, 9 and 15 forming the chambers 10 and 16 are preferably made ofopaque material and are given suitable vents to permit the escape of heat generated by the lamp.

: By the use of my device the lighting produced through the lamp 22 is projected into the plate 1 through the rim of the aperture thereof, some of the light protruding from the bottom and other li ht protruding from the top of said plate. he reflecting surface of the inner housing will assist this protrufrom the top of said plate is reflected by t e reflecting surface of the under side caused to pass through the plate 1, causing a ver beautiful diffused illumination. Surroun ing the plate 1 I have shown a corrugated silientl in the ring 5. y It Wlll be obvious to those skilled in the art that various changes maybe made in-the. embodiment of this invention shown and described without de arting from the spirit of the same. I have's own what I believe to be the best embodiment of my invention. I do not wish to be confined to the embodiment y the housing sections 9 and 9", a

of the frame 7, and

band 20 which holds the, plate 1 reshown, however, but what I wish to cover as my invention is set forth in the appended claims.

Claims:

1. In a light distributer, a transparent plate having an aperture through the same, an opaque housing over said aperture, a frame to support said plate and a lighting medium suitably supported and suspended in said aperture and housing, and adapted to pass rays of light into said plate through its aperture rim.

2. In a light distributer, a transparent plate having an aperture throu h the same, aframe to support said plate, aIighting medium suitably supported and suspended in said aperture, an opaque housin about said lighting element having suitab e openings for the aperture edge of said plate and being provided with air vents therein.

3. In a light distributer, a transparent plate-having an aperture through the same, a frame to support said plate, a lighting medium suitably supported and suspended in said aperture, a housing about said lighting medium having suitable openin s for the aperture edge of said plate and .eing provided with air vents therein, a second housing placed over the first named housing, the said housings forming an air conduit therebetween', said second housing being provided with air vents.

4. In a light distributor, a transparent plate having an aperture through the same, a frame to support said plate, a lighting medium suitably supported and suspended in said aperture, an opaque housing about said lighting medium havin suitable openings for the aperture edge 0 saidplate and being provided with air vents therein, said housing also being provided with light openings, a reflector adapted to receive and.

project the light transmitted through said light openings, asecond reflector adapted to receive and project the reflected light and a transparent screen through which the re-refiected light is passed.

5. In a light distributor, a transparent plate having an aperture throu h the same, a frame to support said plate, a ighting medium suitably supported and suspended in said aperture, an opaque housing about said lighting medium having suitable openings for the aperture edge oi said plate and being provided with air "ents therein, said housing also being provided with light openings, a reflector adapted to receive and project the light transmitted through said light openings, 'a second reflector adapted to receive and project the reflected light, a transparent screen. through which the said re-reflected light is passed, a second housing placed over the first named housing, the said housings forming an air chamber therebetween, said second housing being provided with air vents.
